ROTARY VALVE.

Specification of Letters Patent.

' To all whom it may concern.'

Be it known that I, EUGnNn BALLOU, a citizen of the United States, yresiding at Tolede, Lucas county, Ohio, have invented a new and useful Rotary Valve, of which the following is a specication.

This invention relates to a motor, and more particularly to a valve and the packingTfor said v'alve.

his invention has utility when adapted -to internal combustion motors.

Referring to the drawings: Figure 1 is an elevation with parts broken away showing an embodiment of the invention in an internal combustion engine; Fig. 2 is a section of the device at right angles to the showing in Fig. 1; and Fig. il is a detail view onl an enlarged scale of the rotary valve element, onedmlf being in seeti0n.- The motor cylinder 1 is shown as pio vided with the reeiprocable piston Z having conneetin rod 3 and crank shaft 4. The crank or rive shaft 4 has fixedly mounted thereon the sprocket wheel 5 to drive through the noiseless sprocket chain 6 the sprocket' wheel '7 on the valve shaft S at one-qnarter the speed of the shaft 4. This shaft 8 may have formed thereon aspherical portion 9. one for each. of the cylinders in the group of motors comprising the motor structure. The sphere 9 rovided with a diame'trical port 10 perpendicular to the shaft 8. Packing rings 11 of zone form are arranged on the surface of the valve laterally of port 10, the planes of the rings being parallel to the axis'of the shaft 8 and to' Two of these packthe axis of said port. ing rings 11 are shown on each side of the l port 10. These expansion packing rings 11 each have a step take up joint 12. Housing 13 for the spherical valve member 9 has intake or fuel supply port 14 and e'xhaust gLoirt 15 as to which. the valve port 1G may move in and out of registry in its travel in and out of registry asu to cylinder port- 1.6.

'ilo ignite 'the charge of' fuel in the cylinder,`

the spark plug 17 may be used. Lubricant ducts for the valve shaft 8 supply ample lubricant for the ported spherical valve member 9 as well as its packing rings 11. This spherical valve 9 may more or less nearly approximate a close running it in vthe ported head of cylinderl and theportl ed cap 13.

In operation, the four to one speed reducv`tion allows of such a materially slower?` Vtravel for the valveas to make possible close bearings for the shaft 8. This valve is shown in positionin Fig. '2 of just com plating the 4intake of fuel and about to move toward compression. The elements at the right in Fig. 1 show the piston in compression position and lthe vvalve 9 with its four rings 11 efficiently packing the port 16 as to the ports 14 and 15. At such stage ignition of the charge may occur. As the piston 2 reaches the limit ofits down. stroke the port 16 .is in communication with the port Patented Feb. 20, 1912. Application led November 7, 1910. Serial No. 590,979.

15 by means of the port 10 so that exhaust may occur as the piston 2 has its upward scavenging stroke. The continued travel of the valve 9 brings the port 10 into registry with the fuel supply port 14 to haveth'e fuel drawn in through port 16 as the piston 2 returns from itsscavengin stroke. This intake of fuel lfollowing the discharge of exhaust has a=warming effect upon the fuel in its passage through the hot valve 9. which giving of heat to the fuel where it isfdesired serves to cool the valve 9. With this charge warmed by the valve 9 in the cylinder 1, the pistoia 2 starts on its compression stroke and when compressing the packing rings 11 are in position to hold the' charge during the tiring after which the valve 9 so rotates that travel through its port 10 to exhaust through port 15 may occur. By this four to one operation the valve port 10 has exhaust in one direction of the port at one sca-venge. and an opposite. direction through the saine port at the next scayenge due to the fact that the port 1 0`is turned end for end between its compres-v sions.

In providing packing rings, expansion is readily taken care of to insure a holding o' aressure and elimination of any binding.A '111% disposal of the packing rings in a plane vparallel to the axis of rotation` places lthese rings in their travel transversely of the re1a-.

tive movement between the surfaces packed and accordingly 'insures a movement against binding. The double packing is of'exeeptional value in insurnge'structuregwhich will not leak during the high pressure of expansion. The absence of reeiproeating parts Iin the valve contre] results in producing a noiseless motor of exceeding sim piieity. V

The cylinder and cylinder head may be cooled as found desirable.

'What is. claimed and vit is desired to seeure by Letters Patent is:

1. In an internal combustion engine the combination with a part having; a valve seat, of a valve fitting Within said seat7 such valve comprising a shaft and a valve mem ber of double curvature Carried thereby, such valve member having a port extendinpT centrally therethrough `at right angles to the axis of Said shaft, said seat having oppc 'stely disposed ports adapted .to eoperate with the port in said valve member, and peeking rings. carried by said valve memer on each side of said centrally extending port, said rings lying in planes parallel with said port and with the axis of the shaft.

2. Tn an internal combustion engine, the combination with a part having a valve seat, oia 'valve fitting Within said Seat, such valve comprising a shaft and a valve memher of' double curvature carried thereby, said valve member having a port extending centrally therethrou l1 at rlght angles to said shaft, said seat aving oppositely disposed ports coperating with the port in said valve member, and packing rings carried by said valve member on each side of said centrally extending port, all parte of each of Said rings lying in a true plane, whereby the effects of expansion are rendered uniform throughout the periphery of the ring.

,ln testimony whereof I aix my signature in the presence of two Witnesses` EUGENE BALLOU. iVitnesses:
